Tell me about a time when a short-term pass hides a long-term reliability risk. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed test plan, raw data, failure analysis, and final report and coordinated the action to confirm sample plan, stress condition, duration, acceptance criteria, and failure review. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
